' METHOD or rnonuome ivror on-mc'runns.

Application filed May 26, 1916.

To all whom it may concern Be it known that I, Lnwrs M; ANDERSON, a

citizen of the UnitedStates, residin at Atlanta, in the county of Fulton and tateof Georgia, have invented new and useful Im provements in the Methods of- Producing Motion-Pictures, of which the following is a trated in the accompanying drawings, in-

specification.

Thisinvention relates to the method of producing motion pictures of drawings,

sketches, cartoons, pictures, writing, print-'1 which-- Figure 1, is a general view showing the method of operation; Fig. 2, is a front view of the screen with a drawing showing through it. In Fig. 1, (A) represents the motion picture-camera; (B) the screen, and (C) .the draftsman executing a drawing on the'soreen- In Fig. 2, (B) represents the screen, and (E) a drawing executed on the screen and visible through it. I Instead of photographing in the usual direct manner with a motion picture camera,

drawings, pictures, writing,'or other; matter, wh le being executed by the draftsman or art1st,wh1ch necessarily shows in the resulting motion picture the ,brush or pencil, and

' at;least the hand of the draftsman, I use a method by which the draftsman or artist is rendered photographically invisible, and the drawing, picture, or other matter appears in the resulting motion picture when project- .ed on the exhibition screen without the means of its production visible. I accomplish this result by interposing between the motion picture camera andithe artist or draftsman a screen gnwhlch he executes the drawings or pictures such screen being translucent; or substantially photographically opaque except'to the drawings or pictures executed on its surface, and being adapted to render the draftsman or artist photographically invisible, and to renderthe drawings orpictures photographicall visible through the screen as execute the drawings or pictures being photographed by the motion picture camera as they become visible through the screen.

The screen used to accomplish this result Specification of Letters Patent. Patented. Dec, 18, 191

may be of translucent ground glass of the proper degree of opacity to render'objects' or matter not in immediate proximity or contact with it photographically invisible through it; or a screen may be prepared by backing clear glass with white tissue paper,

' or by coating clear glass with a suitable medium for making it translucent, or substantially photographically opaque except to the drawings, pictures, or other matter executed substantially or wholly photographically invisible. It affords an excellent working surface for oil or water colors, or oil crayons,

and the fiour paste coating beingvery soluble, oil or water colors penetrate 1t lmmedlately, the drawings or pictures as executed becoming clearly visible through the screen on a white background, and giving a su-' pe'rior result in the motion picture negative. L Referring to Fig. 1 in the annexed drawing, my method of procedure in producing a motion picture by this process is for the draftsman or artist, represented by (C), to execute .a drawing or picture on the screen (B), which drawing or picture is immediately visible through the screen and is photographed by the motion picture camera (A) as executed; while the draftsman or artist (C), not being in direct contact with the screen (B) is photographic'ally invisible, and does not appear in the resulting motion picture.

As the-drawing, picture, writing, or other matter is photographed by this method as 'it becomes visible through the screen on the exhibition screen in white on a dark ground this can be accomplished by running a negative film in the pro ecting camera.

In producing motion picture negatives by this method it is desirable to exclude strong v light from the draftsman except such as is transmitted through the translucent screen,

' inorder to prevent any trace of the hand or pen from appearing in the picture. An efi'ective and convenient arrangement for this purpose is to set up the translucent screen, like a window, in an opening in the 10 partition between two rooms the camera and the screen.

I claim: The method of producing motion pictures in whlchdrawings, cartoons, writing, or

other matter are executedon a translucent screen, or on a screen substantially photographically opaque except to the drawings or other matter executed on its surface, said screen during the process of executing the drawings orother matter being interposed between the artist or draftsman and a motion picture camera; such' screen rendering the artist or draftsman substantially or wholly photograghically'invisible, and rendering the drawings or other matter executed on its surface visible through the screen as produced; and the photographing with the motion picture camera of such drawings or other matter'jas they become visible through the screen as executed.
